BIOS Setup Information
4.8 PCI/Plug and Play Setup
This section describes configuring the PCI bus system. PCI (Peripheral Component
Interconnect) is a system which allows I/O devices to operate at speeds nearing
CPU’s when they communicate with own special components.
All of options described in this section are important and technical and it is strongly
recommended that only experienced users could make any changes to the default
settings.
Plug and Play Aware O/S
Set this option to “Yes” if the operating system installed in the computer is Plug and
Play-aware. BIOS only detects and enables PnP ISA adapter cards that are required
for system boot. The Windows 95 operating system detects and enables all other
PnP-aware adapter cards. Windows 95 is PnP-aware. Set this option to “No” if the
operating system (such as DOS, OS/2, Windows 3.x) does not use PnP. You must
set this option correctly or PnP-aware adapter cards installed in your computer
will not be configured properly.
Clear NVRAM
This option is used to clear NVRAM and check or update ESCD (Extended System
Configuration Data) data after system power on. Set this option to No that will not
clear NVRAM and the operation of update ESCD is effective in different ESCD
data comparision. If you select the “Yes” setting, then the BIOS will update ESCD
each time of power on.
PCI Latency Timer (PCI Clocks)
This option is used to control PCI latency timer period (follow PCI clocks). Based
on PCI specification 2.1 or later and PCI bus frequency in system, user can select
different timer to meet their PCI bus environment.
Primar y Graphics Adapter
This option allows user to specify a primary VGA display from two options :
Onboard VGA or PCI VGA card.
